Explicit Rx Indicator frame - 0x91
Description
When a device configured with explicit API Rx Indicator (
AO
=
1
) receives an RF packet, it sends it out
the serial interface using this message type.
Note
If a
is sent to a device with
AO
=
1
, the receiving device receives
a 0x91 frame with the Source endpoint (SE), Destination endpoint (DE), and Cluster ID (CI) that were
set on the transmitting device in Transparent mode, and not the default values.
The Cluster ID and endpoints must be used to identify the type of transaction that occurred.
